Anthony Stewart Painstaking Hand Labor Makes Grand Rapids' Name a Synonym for Fine Furniture Furniture got its start here in days when the log-floating Grand River tapped virgin forests of pine, oak, beech, and maple (page 302). Only scatterings of these woods remain, but imports from all parts of the world now supply the city's 77 furniture makers. Pennsylvania cherry went into this French Provincial chest at the John Widdicomb plant. Twice a year some 3,000 furniture buyers attend the city's furniture markets. wound. His stomach had been laid open. Dr. Beaumont devotedly tended his pa tient several years, but the wound would not heal. Beaumont saw a rare chance-here was a window on an important organ! The doctor won St. Martin's consent to study the digestive processes, including functions of the gastric juices. Some 238 experiments in eight years, part of them in the post hospital, led later to the discovery of pepsin and its action. Beaumont's report, published in 1833, revo lutionized theories of alimentary digestion. Most amazing of all, perhaps-St. Martin lived on unhampered by the hole in his stom ach and died at a ripe old age. Ashore on the "U.P." Returning to Mackinaw City, I picked up my car and rode the Straits ferry to St. Ignace, front door to Michigan's Upper Peninsula, known as the "U.P." At Sault Ste. Marie (French for "St. Marys Leap") the Michigan town faces Ontario's city of the same name across St. Marys River. Between the two, the stream drops Lake Superior's overflow in a foaming rush. Here at the world's busiest locks-ob viously a strategic spot-I found the word of-the-day was "Forbidden!" No photo graphs-not even through fences that sealed off the lock area. Within the restricted zone armed troops manned guard posts. Ore boats were squeezing through the locks. Other vessels, including grain boats and tank ers, steamed upriver or down in the ap proaches. On both banks industrial plants smudged skies that not so long ago knew only Indian campfire smoke. Eighty-five percent of American iron ore passes through the Soo locks en route from Michigan, Wisconsin, Minnesota, and Ontario mines to steel plants of eastern Canada and the Great Lakes States. Called the "most important waterway in the world," the Soo locks carry more cargo than the Panama and Suez Canals combined.
